Failure to follow all safety instructions listed below, can
result in serious personal injury.
Do not allow children or untrained individuals to use this
unit.
Do not start or operate the engine in a confined space,
building, near open windows, or in other unventilated
space where dangerous carbon monoxide fumes can
collect. Carbon monoxide, a colorless, odorless, and
extremely dangerous gas, can cause unconsciousness
or death.
Clear the work area before each use. Remove all objects
such as rocks, broken glass, nails, wire, or loose string
which can be thrown or become entangled in the cutting
line or blade.
Always wear eye protection with side shields marked to
comply with ANSI Z87.1 along with hearing protection
when operating this equipment.
Wear heavy, long pants, long sleeves, boots, and gloves.
Do not wear loose fitting clothing, short pants, sandals,
or go barefoot. Do not wear jewelry of any kind.
Heavy protective clothing may increase operator fatigue,
which could lead to heat stroke. During weather that is
hot and humid, heavy work should be scheduled for early
morning or late afternoon hours when temperatures are
cooler.
Product users on United States Forest Service land, and in
some states, must comply with fire prevention regulations.
This product is equipped with a spark arrestor; however,
other user requirements may apply. Check with your
federal, state, or local authorities.
Never operate this unit on the operator’s left side.
Secure long hair above shoulder level to prevent
entanglement in moving parts.
Keep all bystanders, children, and pets at least
50 ft. away. Bystanders should be encouraged to wear
eye protection. If you are approached, stop the engine
and cutting attachment. In the case of bladed units, there
is the added risk of injury to bystanders from being struck
with the moving blade in the event of a blade thrust or
other unexpected reaction of the saw.
Do not operate this unit when you are tired, ill, upset, or
under the influence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance or exposure
to hot surfaces.
Keep all parts of your body away from any moving part.
To avoid hot surfaces, never operate the unit with the
bottom of the engine above waist level.
Do not touch area around the muffler or cylinder of the
unit, these parts get hot from operation. Contact with hot
surfaces could result in possible serious personal injury.
Always stop the engine and remove the spark plug wire
before making any adjustments or repairs except for
carburetor adjustments.
Inspect the unit before each use for loose fasteners, fuel
leaks, etc. Replace any damaged parts before use.
The cutting attachment should never rotate at idle during
normal use. The cutting attachment may rotate at idle
during carburetor adjustments.
It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. It is presently unknown what, if any, vibrations
or extent of exposure may contribute to the condition.
There are measures that can be taken by the operator to
possibly reduce the effects of vibration:
a) Keep your body warm in cold weather. When operating
the unit wear gloves to keep hands and wrists warm.
It is reported that cold weather is a major factor con-
tributing to Raynaud’s Syndrome.
b) After each period of operation, exercise to increase
blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
d) Keep the tool well maintained, fasteners tightened,
and worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician about
these symptoms.
Mix and store fuel in a container approved for gasoline.
Mix fuel outdoors where there are no sparks or flames.
Wipe up any fuel spillage. Move 30 ft. away from refueling
site before starting engine. Slowly remove the fuel cap
after stopping engine. Do not smoke when refueling.

ers and other occasional users for such general applica-
tions as trimming light and heavy vegetation, etc. It is not
intended for prolonged use. Prolonged periods of opera-
tion can cause circulatory problems in the user’s hands
due to vibration. For such use, it may be appropriate to
use a product having an anti-vibration feature.
GENERAL SAFETY RULES

OPERATING THE TRIMMER
See Figure 10.
WARNING:
Engine housing can become hot during trimmer opera-
tion. Do not rest or place your arm, hand, or any body
part against the engine housing during trimmer operation.
Only hold the trimmer as shown in Figure 10 with all body
parts clear of engine housing. Extended contact with the
engine housing can result in burns or other injuries.
WARNING:
Always position the unit on the operator’s right side. The
use of the unit on the operator’s left side will expose the
user to hot surfaces and can result in possible burn injury.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Always operate trimmer in RUN position. Cut tall grass
from the top down. This will prevent grass from wrapping
around the shaft housing and string head which could cause
damage from overheating. If grass becomes wrapped around
the string head, STOP THE ENGINE, disconnect the spark
plug wire, and remove the grass. Prolonged cutting at partial
throttle will result in lubricant dripping from the muffler.
WARNING:
Always hold the string trimmer away from the body keep-
ing clearance between the body and the product. Any
contact with the housing or string trimmer cutting head
can result in burns and/or other serious personal injury.
CUTTING TIPS
See Figures 10 - 12.
Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 10.)
Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
The curved shaft trimmer cuts when passing the unit from
right to left. The straight shaft trimmer cuts when passing
the unit from left to right. This will avoid throwing debris at
the operator. Avoid cutting in the dangerous area shown
in illustration.
10 — English
OPERATION
Use the tip of line to do the cutting; do not force string
head into uncut grass.
Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the line.
ADVANCING STRING USING THE REEL-EASY
TAP ADVANCE SYSTEM
String advance is controlled by tapping the string head’s
spool retainer on grass while running engine at full throttle.
Run engine at full throttle.
Tap string head on ground to advance string. String
advances each time the head is tapped.
Several taps may be required until string strikes the cut
off blade.
Resume trimming.
NOTE: If the string is worn too short you may not be able to
advance the string by tapping it on the ground. If so, STOP
THE ENGINE, disconnect the spark plug wire, and manually
advance the string.
ADVANCING THE STRING MANUALLY
With the engine off and the spark plug wire disconnected,
push the spool retainer down while pulling on string(s) to
manually advance the string.
GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE
See Figure 13.
The trimmer is equipped with a line trimming cut-off blade on
the grass deflector. For best cutting, advance line until it is
trimmed to length by the cut-off blade. Advance the line when-
ever you hear the engine running faster than normal, or when
trimming efficiency diminishes. This will maintain best perfor-
mance and keep the line long enough to advance properly.
11 — English
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.

shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal
injury.

amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recom-
mend that only qualified service technicians perform this
service.
The spark arrestor must be cleaned or replaced every 50
hours or yearly to ensure proper performance of your prod-
uct. Spark arrestors may be in different locations depending
on the model purchased. Please contact your nearest service

WARRANTY
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The U.S. Environmental Protection Agency (EPA), the California Air
Resources Board (CARB), and Techtronic Industries North America,
Inc., are pleased to explain the Emissions Control System Warranty
on your new 2013/2014 small off-road engine. In California, new
equipment that uses small off-road engines must be designed, built,
and equipped to meet the state’s stringent anti-smog standards. In
other states, new small off-road engines must be designed, built, and
equipped at the time of sale to meet the U.S. EPA regulations for small
off-road engines. The small off-road engine must be free from defects
in materials and workmanship which cause it to fail to conform with
U.S. EPA standards for the first three years of engine use from the date
of sale to the ultimate purchaser. Techtronic Industries North America,
Inc., must warrant the emission control system on your small off-road
engine for the period of time listed above provided there has been no
abuse, neglect, or improper maintenance of your small off-road engine.
Your emission control system may include parts such as the carbure-
tor or fuel injection system, the ignition system, catalytic converters,
fuel tanks, valves, filters, clamps, connectors, and other associated
components. Also included may be hoses, belts and connectors, and
other emission-related assemblies.
Where a warrantable condition exists, Techtronic Industries North
America, Inc., will repair your small off-road engine at no cost to you,
including diagnosis, parts, and labor.
MANUFACTURER’S WARRANTY COVERAGE
This 1995 and later small off-road emissions control system is war-
ranted for three years. If any emission-related part on your engine is
defective, the part will be repaired or replaced by Techtronic Industries
North America, Inc.
OWNER’S WARRANTY RESPONSIBILITIES
(a) As the small off-road engine owner, you are responsible for the
performance of the required maintenance listed in your operator’s
manual. Techtronic Industries North America, Inc., recommends
that you retain all receipts covering maintenance on your small
off-road engine, but Techtronic Industries North America, Inc.,
cannot deny warranty solely for the lack of receipts or for your
failure to ensure the performance of all scheduled maintenance.
(b) As the small off-road engine owner, you should be aware, however,
that Techtronic Industries North America, Inc., may deny you warranty
coverage if your small off-road engine or a part has failed due to abuse,
neglect, improper maintenance, or unapproved modifications.
(c) You are responsible for presenting your small off-road engine to an
authorized service dealer as soon as a problem exists. The warranty
repairs should be completed in a reasonable amount of time, not to
exceed 30 days.
If you have any questions regarding your warranty rights and respon-
sibilities, you should contact a Techtronic Industries North America,
Inc., Customer Representative at 1-800-860-4050.
DEFECT WARRANTY COVERAGE REQUIREMENTS
(a) The warranty period begins on the date the engine or equipment
is delivered to an ultimate purchaser.
(b) General Emissions Warranty Coverage. Techtronic Industries North
America, Inc., warrants to the ultimate purchaser and each subsequent
purchaser that your small off-road engine is designed, built, and
equipped at the time of sale to conform with all applicable regulations
adopted by the California Air Resources Board or the United States
Environmental Protection Agency; and that it is free from defects in
materials and workmanship which cause the engine to fail to conform
with applicable regulations for a period of three years from the date
the small off-road engine is purchased by the initial purchaser. Any
replacement part or service that is equivalent in performance and
durability may be used in non-warranty maintenance or repairs, and
shall not reduce the warranty obligations of Techtronic Industries
North America, Inc.
(c) The warranty on emissions-related parts will be interpreted as
follows: Any warranted part that is not scheduled for replacement as
required in the Maintenance Schedule is warranted for three years. If
any such part (including any part that is scheduled only for regular in-
spection) fails during the period of warranty coverage, it will be repaired
or replaced at any RYOBI
® Authorized Service Center at no charge.
Any such part repaired or replaced under warranty will be warranted
for the remaining warranty period. A statement to the effect of “repair
or replace as necessary” would not reduce the period of warranty
coverage. Any warranted part that is scheduled for replacement as
required maintenance in the Maintenance Schedule is warranted for
the period of time prior to the first scheduled replacement point for that
part. Any such part repaired or replaced under warranty is warranted
for the remainder of the period prior to the first scheduled replace-
ment point, and will be repaired or replaced at any RYOBI
® Authorized
Service Center for no charge until that replacement point is reached.
Techtronic Industries North America, Inc., shall remedy warranty de-
fects at any authorized RYOBI
® Authorized Service Center, including
any distribution center that may be franchised to service the subject
engines. Any diagnostic work done at a RYOBI
® Authorized Service
Center shall be free of charge to the owner if such work determines that
a warranted part is defective. Any manufacturer-approved or equiva-
lent replacement part may be used for any warranty maintenance or
repairs on emission-related parts, and must be provided free of charge
to the owner if the part is still under warranty. Techtronic Industries
North America, Inc., is liable for damages to other engine components
caused by the failure of a warranted part still under warranty.
Add-on or modified parts that are not exempted by the California Air
Resource Board may not be used. The use of any non-exempted add-
on or modified parts will be grounds for disallowing a warranty claim.
Techtronic Industries North America, Inc., will not be liable to warrant
failures of warranted parts caused by the use of a non-exempted
add-on or modified part.
The Emission Parts List specifically defines the emission-related war-
ranted parts. Techtronic Industries North America, Inc., will provide
any documents that describe its warranty procedures or policies
within five days upon request by the California Air Resources Board.
